Chrysanthemum plant named ‘Syema Oranbi’

ABSTRACT

A new  Chrysanthemum  plant named ‘Syema Oranbi’ particularly distinguished by the large, yellow and orange bi-colored inflorescences, dark yellow-green foliage, nicely mounded plant habit, with a natural flowering season of about mid-October.

Latin name of the genus and species of the plant claimed: Chrysanthemum×morifolium.

Varietal denomination: ‘Syema Oranbi’.

BACKGROUND OF THE NEW PLANT

The present invention comprises a new Chrysanthemum, botanically known as Chrysanthemum×morifolium, and hereinafter referred to by the variety name ‘Syema Oranbi’.

‘Syema Oranbi’ is a product of a planned breeding program. The new cultivar has large, yellow and orange bi-colored inflorescences, dark yellow-green foliage, nicely mounded plant habit, with a natural flowering season of about mid-October.

‘Syema Oranbi’ originated as a natural whole plant mutation of ‘Empire Emma’, U.S. Plant Pat. No. 20,196. ‘Syema Oranbi’ was discovered and selected by the inventor as a single flowering plant within a population of the parent cultivar in a controlled breeding program in Alva, Fla. in November 2007. The parent cultivar ‘Empire Emma’ has larger inflorescences with less orange color in the inflorescence, little larger plant habit, and a natural flowering season that is a little faster.

The first act of asexual reproduction of ‘Syema Oranbi’ was accomplished when vegetative cuttings were propagated from the initial selection in December 2007 in a controlled environment in Alva, Fla.

BRIEF SUMMARY OF INVENTION

Horticultural examination of plants grown from cuttings of the plant initiated in December 2007, and continuing thereafter, has demonstrated that the combination of characteristics as herein disclosed for ‘Syema Oranbi’ are firmly fixed and are retained through successive generations of asexual reproduction.

‘Syema Oranbi’ has not been observed under all possible environmental conditions. The phenotype may vary significantly with variations in environment such as temperature, light intensity and day length.

A Plant Breeder's Right for this cultivar was applied for in Canada on Apr. 9, 2010 (No. 10-6930). ‘Syema Oranbi’ has not been made publicly available more than one year prior to the filing of this application.

The following traits have been repeatedly observed and are determined to be basic characteristics of the new variety. The combination of these characteristics distinguishes this Chrysanthemum as a new and distinct variety.

BRIEF DESCRIPTION OF THE PHOTOGRAPHS

The accompanying photographic drawing shows typical flower and foliage characteristics of ‘Syema Oranbi’ with colors being as true as possible with an illustration of this type. The photographic drawing shows a flowering potted plant of the new variety.

DETAILED BOTANICAL DESCRIPTION

The plant used for the photographs were about 16 weeks old, grown in Monroeville, N.J., in an outdoor trial. Rooted cutting were grown in a nine inch pot with no terminal pinching of the apices. The photograph was taken in mid-October 2010 in New Jersey.

The plant descriptions and measurements were taken in Gilroy, Calif. in May 2010 under natural light. Plants were grown in 4.5 inch pots, under conditions which approximate those generally used for potted Chrysanthemum trials in a greenhouse. These plants used in the descriptions were about 10 weeks old.

Color references are made to The Royal Horticultural Society Colour Chart (R.H.S.) 2001.
